The Diamond T GS8L90SR torque converter will perform similarly to stock for 8L90 applications. This is a factory replacement-style converter designed to maintain OEM drivability characteristics while offering improved durability.
The GS8L90SR features a furnace-brazed impeller and turbine, bias-applied lock-up clutch, and needle bearing between cover and turbine for extended life compared to stock. It maintains stock stall speed and daily driving performance for 2014-2019 GM vehicles with 4.3L, 5.3L, and 6.2L gas engines using the 8L90 transmission (non-start/stop versions).
